Part Creation Works on the premise that a sketch is drawn and then a feature creates the 3D component I Sketch I Be aware of the origin can be helpful for revolved parts or to minimize the amount of reference planes that must be added I Use of center lines to achieve symmetry I Smart dimensioning Relations hold control and click the lines you need know what the relations mean and what they can achieve Creation of planes flat surfaces are planes so the reference plane feature does not always have to be utilized R are in the features menu Know how to insert a picture and to make a sketch block from it I Features I Extrude basic extension of sketch I Be aware of what the options of extrude can do ie extrude from midplane offset thin feature selected contours etc I Revolve extrudes sketch around a central axis Very useful with circularcylindrical parts ie rockets tire rims lamp shades cups bowls etc I Sweep Requires two individual sketches The first is for a profile the shape of the duct beam etc Only one profile is required The second sketch is the path which is the route the sketch will take The profile and path are drawn on two perpendicular planes so be aware of placement Also use this feature for irregularly shaped tubes or objects with the same thickness think of the lamp fixture stem I Loft Similar to sweep but does not require a path sketch though guide curves can be added if desired Allows you to transition between two irregularly shaped objects or two different sized objects I Can be done between two surfaces two sketches or between a sketch and a surface Cuts Most features have cut versions of themselves that remove material rather than add They work on similar principles I Hole Wizard Useful for creating holes to accommodate standard fasteners bolts and screws I Fillet Rounds off a sharp corner or edge I Linear or Circular pattern Useful for creating repeated copies of a feature I Rib For adding thin walls by extruding an open or closed sketch contour I Draft Creates angled edges I Choose a reference surface then choose the edges to draft set particular angle I Click apply I Shell Makes an object hollow ora mold I Choosing a single surface scoops out the material to a particular thickness from each edge I Choosing two surfaces on opposite will enable you to create a passage way I Know the difference between shelling outward or inward in terms of smart dimensioning I Mirror For duplicating a feature across a plane of symmetry I Reference Geometry Allows you to create your own planes axes or points in your model I Dome Adds a semisphere on a flat surface I Surfaces I Extruded Revolved Swept Lofted and Fillet surfaces are analogous to their solid feature counterparts I Also know how to use Boundary Filled Planar and Offset surfaces I Know how to Trim or Extend surfaces and how to Knit surfaces together I Know how to Thicken surfaces into solid parts Assemblies and Drawings I Assemblies I Know how to use different Mates to assemble your models I Standard Mates Coincident Parallel Perpendicular Tangent Concentric Offset etc I Mechanical Mates Cam Gear Universal Joint I Be able to change the appearance of a part color transparency and assign materials I Create different Configurations of an assembly in the same file I Create the Exploded state of an assembly I Make sure you know how to use Pack and Go to save your assembly into a zip file I Drawings I Know how to choose the correct sheet size and format I Know how to create multiple sheets pages in one drawing I Insert standard views Front Right Top Isometric I Show an Exploded View which you defined in the assembly model I Add a Bill of Materials and balloons remember the AutoBalloon button I Create a Projected View Auxiliary View Section View and Detail View I Change the display state appearance and scale size of a view I Create dimensions I Add your name or other text in the title block quotEdit Sheet Formatquot I Make sure you know how to create a PDF of your drawing Advanced Tools I Set up and run a simple FEA analysis and show results stress strain displacement I Perform a Motion Study and show results Trace Path of the motion plot of velocity or acceleration etc I Produce a Photoview 360 rendered photo ofa model
